Commit a65e7bfcd7
broke the UML build with
the following error -
In file included from fs/proc/kcore.c:17:
include/linux/elfcore.h: In function 'elf_core_copy_task_regs':
include/linux/elfcore.h:129: error: implicit declaration of function 'task_pt_regs'
Fix this by restoring the previous behavior of returning 0 for all arches
like UML that don't define task_pt_regs.
